"What Christ purchased for us, was that we might have communion with God in his good, which consists in partaking of or having communion of the Holy Ghost, as I have shown. All the blessedness of the redeemed consists in partaking of the fullness of Christ, their head and Redeemer, which, I have observed, consists in partaking of the Spirit that is given him not by measure. This is the vital sap, which the branches derive from the true vine; this is the holy oil poured on the head, that goes down to the members. Christ purchased for us that we should enjoy the love, but the love of God flows out in the proceeding of the Spirit; and he purchased for them that the love and joy of God should dwell in them, which is by the indwelling of the Holy Spirit. The sum of all spiritual good which the saints have in this world, is that spring of living water within them which we read of, John 4:10–14; and those rivers of living waters flowing from within them which we read of, John 7:38–39, which we are there told is the Holy Spirit. And the sum of all happiness in the other world, is that river of living waters which flows from the throne of God and the Lamb, which is the river of God's pleasure and is the Holy Spirit; which is often compared in Scripture to water, to the rain and dew, and rivers and floods of waters (Isaiah 44:3, Isaiah 32:15, Isaiah 35:6–7, Isaiah 41:17–18 compared with John 4:14, and Isaiah 43:19–20). The Holy Spirit is the purchased possession and inheritance of the saints, as appears, because that little of it which the saints have in this world is said to be the earnest of that purchased inheritance. Ephesians 1:13–14, "In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory." 2 Corinthians 1:22, "Who hath also sealed us, and given the earnest of the Spirit in our hearts"; and 2 Corinthians 5:5, "Now that he hath wrought us for the selfsame thing is God, who also hath given unto us the earnest of the Spirit." 'Tis an earnest of that which we are to have a fullness of hereafter. The Holy Ghost is the great subject of all gospel promises, and therefore is called the Spirit of promise. Ephesians 1:13, "In whom also after that ye believed, ye were sealed with that holy Spirit of promise." He is called "the promise of the Father" (Luke 24:49). The Holy Ghost being a comprehension of all good things promised in the gospel, we may easily see the force of the Apostle's arguing, Galatians 3:2, "This only would I know, Received ye the Spirit by the works7 of the law, or by the hearing of faith?" So that in the offer of redemption, 'tis of God" Jonathan Edwards 'Treatise On Grace' https://www.monergism.com/thethreshold/sdg/edwards/edwards_treatisegrace.html
